zzzzzzzzzzz u guys make it sound like such a big problem but of the many cooler's i've bought many of them have bases that are even worse.
If that's how the base was when anandtech reviewed it, that just makes me think the cooler is even better than the review after i lap it.
I installed mine yesterday as is and it performs better than my Tuniq did lapped. They grooved their base for a reason and so I left it as is and I am happy that I did so.
Yes its nickel plated copper.Quote:

I honestly don't understand how you guys praise thermalright so much on the quality of their heatsink design but then act like they don't know what they're doing when it comes to the base. I checked the base with a razor blade and its completely flat, much more so than my old Tuniq or the Zalman I used on my old AMD machine. I have no plans on lapping and I really doubt anyone will see any improements in doing so.
Cool man, what kind of load temps are you getting (TAT or CoreTemp)? And what ever they with your old HS?
Any pics of your setup TouGe?
Please report ur temps before and afterQuote:

I think the fine pattern actually creates a better reflection. Try it out: if you put an object close near the base, it will actually reflect very nicely, despite being a fairly rough finish. It seems to be the same pattern as those flat magnifying glasses you see around, I wonder if its some sort of optical illusion.
As you start lapping it at lower grits, 220, 400, the reflection actually becomes worse. Evens out at about 800. Starts to reflect nicely at 1000.

I don't care that some phone guy getting paid minimum wage claims to be an expert on heat transfer. they tell you that because they don't want you to find flaws in thier products, it's brand managment. Microsoft does the same thing, if your software crashes and you call them for help, they will tell you it's actually a feature, and you should thank them for it.
grooves aren't better. if someone laps to 600 grit and gets worse temps, i owe them $10.
yeah lapping with some glass is really important especially lapping both the IHS and the heatsink, if you don't then you aren't getting full contact guarenteed
and the grit doesn't even matter, lap to 320 and you'll still probably get better temps
:slapass:
Just wanted to update the tread. I ended-up lapping the HS and found out that it was indeed concave. It's nice and flat now. I also lapped the q6600 CPU which I found out was also concave so it's no wonder I had higher temps.
I made several threads throughout the process:
Ultra-120 Extreme lapping
Q6600 lapping part 1
Q6600 lapping part 2
You'll find a table of before/after temps, a summary of what I did as well as some pics in those 3 threads. If you're thinking about lapping either your CPU or HS, I'd encourage you to google around (tons of great guides out there), and/or ask in here. Lapping either of them is actually pretty darn simple and rewarding temp wise.
Hmmmm, lapping a 330quid chip is a little bit out of my league.
No it isn't. You just need to use your head and work slowly and carefully. I have lapped the IHS 4 times totally (I was playing it safe, making sure I wasn't taking too much material off the thing). I think if you start with a pretty high grit paper like I did (800 then 1000), it makes it much easier to keep things flat and not take off too much at one time. I see you're @ 9x333 also cooled with an ultra-120.Quote:

Now you have no warrenty. All for a few degree's, it's not worth it IMO.
Very true, I suppose it's not for everyone (just those of us suffering from OCD). Can you post an answer to my questions from the post before your last reply? I'm curious since I don't know anyone else with a q6600.Quote:

Erm my idle temps are as iam typing this 32, 29, 27, 28. Load temps in orthos are around 55-65C.
7x440 w 1.41 Vcore. Room is 21-23.
Will it take a 32mm fan?
Was thinking of the IFX-14...Quote:

Yes, this is normal. It is due to the retention bracket design. If you want to read more about, it Anandtech has an updated review of the retail version where they mention this also.Quote:

Definately worse having a grooved finish. Christ when using the mills in the lab i can get a better finish on aluminium blocks im shaping.Quote:

In an ideal world we should be able to find out the maximum particle sizes in the pastes we use, and try to attain a surface finish matching the roughness for those particles, to optimize heat transfer.
